biotite An important rock-forming silicate mineral; a member of the mica group K 2 (Mg,Fe) 6 [Si 3 AlO 10] 2 (OH,F) 4, in which the Mg/Fe ratio is less than 2:1; biotite forms a series with phlogopite (of similar composition, but with Mg/Fe greater than 2:1) and may have Fe 3+, Ti 4+, and Al 3+ also present in the formula; sp. gr. 2.7–3.3 .
The high iron content, which imparts dark colors, rules out biotite from many industrial uses. However, because biotite is abundant in granitic rocks, pegmatites, and schists that are also associated with the more desirable muscovites, the mineral is important for exploration. Biotite is mica of little commercial value.

There is no doubt that mineral and mining companies have remained part of the biggest companies in South Africa. Despite a significant hit on these companies a few years ago which led to the shrinking of many of them, it is interesting seeing them pick up with records of unprecedented growth.
What is Biotite? Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic rocks.These include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others.These micas vary in chemical composition but are all sheet silicate minerals with very similar physical properties.

The name "biotite" is used in the field and in entry-level geology courses because these minerals generally cannot be distinguished without optical, chemical, or x-ray analysis. Biotite is a primary mineral found in a wide range of crystalline igneous rocks such as granite, diorite, gabbro, peridotite, and pegmatite.
The remaining 20 to 25 percent comprises hornblende-biotite gneiss, amphibolite with or without pyroxene, and pegmatite. Granitic gneiss is composed of quartz, plagioclase, biotite, and microcline. Minor and accessory minerals are garnet, muscovite, magnetite, ilmenite, sphene, apatite, and zircon.
